Why do some animals migrate over long distances?

Migration is typically driven by the search for food, suitable breeding grounds, or the need to escape unfavorable environmental conditions. Many birds, for example, migrate to warmer climates in the winter to ensure access to food. Similarly, sea turtles travel thousands of miles to return to the beaches where they were born to lay their eggs. Migration helps animals maximize their chances of survival by ensuring they are in optimal environments for feeding, breeding, or avoiding extreme weather.
